I try to Integrating formspider with GlassFish, i already read and follow the instruction on http://ronr.blogspot.com/2012/07/how-to-setup-formspider-apex.html.
so far i was able to display the formspider welcome, but when i tried to call the formspider IDE it's return error.
it's possible to set formspider war 1.5.0 with formspider 1.6.0 ?

I think you have problems with connection to DB.
I try integrate with GF3 and GF4 using this instruction http://ronr.blogspot.com/2012/07/how-to-setup-formspider-apex.html.
With GF4 i get error when i try edit or create panel . Error: "cvc-elt.1: Cannot find the declaration of element 'root'. At Line: 1 , Column: 147"
For example. i make NEW application. Create panel "TEST" , source: <panel> </panel> and get same error.

But if you importing project from another FS , project working , but can't edit :)
